I ve tried pb blaster and liquid lube.
Pb blaster good for door locks.
Time will tell long term.
Seemed to work in the short term on my exterior lock and some old bedroom door knobs.

Get a can of pb blaster and use a straw and stick the straw in the door lock and spray the lock.
I suggest wd40 which i have used in outside door locks and should not harm any electrical wiring it might get into vs comments on graphite in earlier posts not being good for electrical contacts.
Protects against further rust and corrosion.
Teflon fluoropolymer reduces friction wear.
Also the latch pivot straps get gummed up and become hard to move the handles when opening and closing.
It is considered as the most effective penetrating oil for aluminium coupled with its affordable price.
In some instances its extreme pressure agents make it a suitable replacement for grease.
That s more troublesome to me than the hinges.
Won t accumulate dust dirt.
So this year i took the lock set apart and conditioned the gasket as well as used some dumb dumb sticks the black stuff used to mount the windshield between the lock and the gasket as well as between the body and the gasket.
If you need to move something like wheel bearings door hinges and many more pb blaster has it covered.
That s what i ve considered doing on mine.
And it s definitely nothing like original pb blaster.
Guess what no more moisture on the key and the lock has yet to freeze this year.
It seems to help for a short time and then things start binding again.
I have had good luck spraying a little pb blaster in there it really works well.
The 1 selling penetrant since 1957 pb b laster quickly busts loose rusted or frozen parts caused by rust and corrosion.
Formulated with teflon fluoropolymer to help reduce friction and wear.

It seems to have a highly volatile acetone mineral spirit denatured alcohol solution that left a white teflon powder behind.
Breaks free rusted or frozen parts.
